Description

Papra’s webhook delivery system contains an SSRF protection bypass that allows any authenticated organisation member to cause the server to make HTTP requests to internal addresses — loopback, link-local, and RFC-1918 ranges. The SSRF protection validates the registered webhook URL but ignores redirect destinations.

Recommendation

Update the @papra/webhooks package to the latest compatible version. Followings are version details:

  • Affected version(s): < 0.3.3
  • Patched version(s): 0.3.3
